Missing/Power Loss!

Still sounds like timing..... Intake valves are open when the plug fires..... Timing chain??

I won't rule it out, but I think a sticking valve(s) might do the same thing. I put in new timing gear system about 6 or so years ago, don't want to do that again.

Could be a broken valve spring... Nothing is easy at this point!

I would verify the firing order around the rotor cap, just in case someone is playing with you...

Then do a compression test before pulling the rocker arm cover.

I don't want to jinx it, but after about 15 years with it, more often than not it is really something relatively easy. Yes, there have been a few painful fixes, but.........(he says with his fingers crossed)

KISS method.
Pull the dizzy cap. Check the points are ok. Once pulled into the garage and car was fine. Yet car wouldn't run the next day.
Points had broken up. How the hell it ran before is beyond me.

I have a Crane ignition in there, but I will check for any broken bits.

What did you find out?

1. Son left for TX and I now have a spare Cherokee.
2. End of the school year and I have no possible excuses for putting off grading.
Hope to check the firing order first tomorrow, and then look for debris in the dizzy, and if nothing, I'll probably adjust the valves. With the rocker cover off I can see if there are any obviously damaged valve stems or springs.

Ugh!! Grading.....

Was just curious....

Best!!
